3S 10A 12V 18650 Lithium Battery Charger Board Protection Module

The 3S 10A 12V 18650 Lithium Battery Charger Board Protection Module is designed for use with a series combination of three 18650 batteries or polymer lithium batteries. This module can charge lithium batteries with a rated voltage of 10.8V for polymer batteries, 11.1V for 18650 batteries, or 12.6V for fully charged batteries. It also provides protection against over-charging, over-discharging, over-current, and short circuits to ensure safe operation.

With a maximum discharge current of 10A, this protection module is ideal for applications that require high power. It is suitable for a wide range of 12V devices, including rechargeable massagers, LED emergency lights, solar street light batteries, and backup power sources.

Key Features:

• Wide Battery Compatibility: Compatible with 18650 lithium-ion batteries or polymer lithium batteries.
• Over-Charge/Over-Discharge Protection: Safeguards against overcharging and deep discharging, enhancing battery life and safety.
• Over-Current Protection: Protects against excessive current draw to prevent damage to the module and battery.
• Short-Circuit Protection: Automatically detects and protects the system in case of a short circuit.
• Current Limit: Discharge current up to 10A, providing reliable power for high-demand applications.
• Energy Efficient: Resting current is less than 30µA, ensuring minimal power consumption during idle times.
• Self-Recovery: The module includes a self-recovery delay after protection triggers, ensuring easy recovery from fault conditions.
• Long Lifespan: Effective lifetime of over 30,000 hours for long-term reliability.
• Low Internal Resistance: Less than 100mΩ for efficient power transfer.

Important Notes:

• Wiring Instructions: Follow the wiring diagram carefully to connect the batteries. Do not intentionally short-circuit.
• Battery Charging: Charge each battery individually before connecting them in series if they have different voltage levels. Always test the battery groups to ensure they have equal charge.
• Warning: This protection board does not support lithium iron phosphate batteries or applications such as xenon lamps, cordless drill batteries, electric fishing batteries, or electric bike batteries. Make sure the module matches your specific requirements before use.
